Hi,Im using stm32h7 mcu for my project.Which is an iot product.I need to use low power mode on it i need to wake the mcu using an gpio external interrupt or either by an uart .Device is switch to some mode with a constant current consumption which i...
With STM32L071, I've been fighting a problem of losing UART RX characters. The RX path uses HAL_UART_ReceiveIT to queue a single character buffer, and then re-queues it from HAL_UART_RxCpltCallback. The received character is then stored in a software...
I was promised the recording, presentations and a voucher but never received any. Where can I get thesr?

Greetings,I have been working with the STM32F407ZG and a KnobG Click from MikroElectronica. I read the datasheet for the PCA9956B and have managed to address the device successfully at the address of 0x70. Now then according to the usage I have seen ...
Hey all, I've been working on this issue for about a week and am still not gaining any traction. I am trying to set up the RMII for the STM32H723ZG eval board (I cannot use the MII as we are using the pins for other peripherals).The LwIP TCP echo wor...
Hi everyone,Im havinga annoying problem, im trying to inialize the DMA with the ADC , on my custom board. when a initlize it, it works fine, i get the 3 values of the trhee adc channel stored on a buffer. But the Systick timer goes crazy. i get way m...
please let me know my coding is correct ,whether usage of my exti is correct while (1) { HAL_Delay(300); // MAINS INPUT Adc_Mains(); HAL_ADC_Start(&hadc1); HAL_ADC_PollForConversion(&hadc1,1000); Main...
I couldn't able wakeup the system after standby (wakeup should be switching ON mains ) the wakeup pin PA2 is connected to mains pin configured for pwr wakeup. int main(void) { /* USER CODE BEGIN 1 */ /* USER CODE END 1 */ /* MCU Configuratio...
Hello All, Just some context on what I'm trying to achieve. I have a board which has 4 NTCs creating a potential divider which is then sampled by the ADC. The supply to this potential divider is from one of the IO pins of the STM32F030 (SENSO...
